Pinterest button for “On Media” does not default to page title if empty

When the Pinterest share button is enabled in the “On Media” settings, the share link is invalid, resulting in a Header overflow error when the Pinterest Description is blank.

The reason for the error is that the entire contents of the page is used for the description query parameter when the Pin Description field is left empty. It does not default to the post title as suggested in the documentation.

I’m seeing this behaviour with both of the Pinterest Description Source settings.

When the Pinterest Description is explicitly added to the post/media, then the sharing works as expected.

Can we expect a fix for the fallback description soon?

Thanks,
Carla
